UITextField 无法以编程方式工作?
UITextField is not working programmatically?
我以编程方式创建 UITextField
一切正常,但我的 UITextField
没有编辑,即当我尝试点击 UITextField
它在这里不起作用我的示例代码,
CGRect frame = CGRectMake(16, 281, 288, 47);
cycle = [[UITextField alloc] initWithFrame:frame];
cycle.placeholder = @"Cycle Number";
cycle.textColor = [UIColor blackColor];
cycle.font = [UIFont systemFontOfSize:17.0];
cycle.borderStyle = UITextBorderStyleLine;
cycle.autocorrectionType = UITextAutocorrectionTypeYes;
cycle.keyboardType = UIKeyboardTypeDefault;
cycle.clearButtonMode = UITextFieldViewModeWhileEditing;
cycle.delegate = self;
cycle.text = @"";
[self.view addSubview:cycle];
'UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(10, 200, 300, 40)]; textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = @"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.delegate = self;
[self.view addSubview:textField];'
Below delegate methods must use
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self endEditing];
[textField resignFirstResponder];
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
[self beginEditing:textField];
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
// [self endEditing];
}
I hope you it is useful for u
